4 Claims.

The purpose of the present invention is to provide an eyelet'setting tool by which one portion of the entering end of an eyelet barrel will be turned into the mouth of the barrel to form a well defined retaining lip while other portions are being turned out and clenched to secure the eyelet in the work piece intended to receive it. The lip thus formed in the mouth of the barrel may serve as a detent to retain some other element, for example, a movable catch. Such an example is shown herein, the catch member being a part of a device intended to hold the handle of a broom or mop standing against a wall.

The tool herein illustrated as embodying the invention is designed to operate on an eyelet having an unscored circular barrel, but to score the barrel at two points before actually forming the lip and doing the clenching. The tool is preferably provided with a tapering pilot having two sharp scoring edges that diverge enough to score nicks in the entering end of the barrel. These edges continue from the pilot across the ends of an arcuate upsetting surface by which the segments are torn apart and by which the longer segment is turned out and clenched. The tool also has a concave cylindrical upsetting surface by which the shorter segment is turned in and converted into a revolute lip.

Referring to the drawing,

Fig. 1 is a perspective view (enlarged) of a tool embodying the invention in a form intended for circular eyelet barrels;

Fig. 2 is a perspective view of a typical eyelet having a circular unscored barrel;

Fig. 3 is a sectional view of cooperative eyelet setting tools in the act of clenching an eyelet in a work piece and forming an inwardly curled hp at the lower end of the barrel, the lower tool having the features shown in Fig. 1;

Fig. 4 is an end elevation of a clenched eyelet as viewed from the flange end thereof;

Fig, 5 is an end elevation of the clenched end of the same eyelet;

Fig. 6 is an end View of the tool shown in Fig. 1, the pilot portion thereof being in section;

Fig. 7 is a top plan view of a broom holder attached to a section of an upright such as the stile of a door, the broom holder including a hinged bail or hand held in closed position by the lip of a clenched eyelet; and

Fig. 8 is a perspective view of the bail included in Fig. '7.

As shown in Figs. 1 and 6, the tool I0 has an arcuate groove formed by a concave upsetting surface II, a straight groove formed by a concave cylindrical upsetting surface I2, a pilot portion I3 bounded by the'surfaces II and I2, and two sharp scoring edges l5 extending along the pilotportion to its root and thence across the ends of the concave surface 'I I. tion is circular in section except at one side I4 where a segment thereof is cut away to provide the'scoring edges I5 and to enable the pilot portion and an eyelet to be separated after the lip has been formed. Moreover, the pilot is tapered from its root to its outer end, the latter being small enough to go into the entering end of an eyelet barrel I6 (Fig. 2) of the base of the pilot portion.

' The eyelet barrel 16 is circular in section and less diameter than has no scoring prior to encountering the edges I5, but it may have a flange or head I1. of any preferred design. As theenteri'ng end of the barrel I6 traverses the pilot portion I3, it becomes slightly dilated and distorted thereby, particularly at the points where the dilation is due to divergence of the scoring edges I5. These edges produce sharply defined nicks in the entering end before the latter actually encounters the upsetting surfaces II and I2, and these nicks insure splitting or tearing the metal of the entering end at the junctions of the upsetting surfaces and nowhere else. Consequently, while the longer segment of the entering end is being curled outwardly by the surface II its ends are torn away from the shorter segment entering the straight groove formed by the cylindrical surface I2.

Since the two segments of the entering end are freed, one from the other, as the upsetting progresses each segment may follow its own upsetting surface without being drifted by the other. The outer boundary of the cylindrical surface I2 is tangential to the path followed by the segment that bridges the face I4. Consequently, that segment is deflected inwardly, straightened and curled toward the flange II until it becomes a revolute lip 20 (Figs. 4 and 5) partially obstructing the mouth of the barrel I6. At the same time, the longer segment is deflected outwardly and curled toward the flange I! to provide a clenched portion I8. The torn portions I9 (Fig. 5) are the results of the nicks produced by the scoring edges l5.

An eyeleting machine of the type shown in United States Letters Patent No. 1,369,021, may be used to insert and clench eyelets with the tool II] and with the results illustrated herein. That patent was granted February 22, 1921, on application of P. R. Glass. As shown in Fig. 3 here- The pilot por-,

in, the tool is aflixed to a stationary support 2| and is located in line with a vertically movable inserting tool 22 carried by a plunger (not shown) and provided with a spring-pressed spindle 23 adapted to pick eyelets one at a time from a raceway (not shown).

Fig. 7 illustrates one example of a product in which an eyelet has special utility when provided with a retaining lip 20. -This product is designed to be attached to a wall of a room or closet or to a stile 25 of a door casing to hold the handle of a broom or mop. It comprises a base 26, a bail 21, a hinge 28 and an eyelet clenched as above described. The bail is a strip of resilient sheet metal in one end of which a slot 29 is .pro* vided to receive the hinge 28. The other end of the bail is provided with a tongue 30 adaptedto enter the throat of the eyelet, and the tongue is curved to enable its tip to catch the lip 20 of the eyelet, the lip being at the side away from the hinge. To insure the desired cooperation of the lip and the'tongue 30 the normal curve of thebail spreads the arms a little farther than the distance between the hinge and the lip, but the arms may be easily sprung toward each other with finger pressure to insert the tongue into the eyelet or to'release it.

Nails 3| may be driven into the supporting element 25 to attach the base 26. If th base comprises two or more layers of material the ends of the hinge may lie between them. Thick cardboard is a suitable material for the base, not only for-economy but also it may be easily punched to provide holes for the nails, the hinge and the eyelet. When two layers are used the back layer may be attached to the front layer with an adhesive after the bail has been attached but before the eyelet is inserted.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. A tool for clenching an eyelet, the tool having' an arcuate upsetting surface arranged to turn out and clench a segment of a circular eyelet barrel, a cylindrical upsetting surface arranged to turn in-and curl another segment of the barrel, and sharp scoring edges at the ends of said arcuate surface. j

2. A tool for clenching an eyelet, the tool having an arcuate upsetting surface arranged to turn out and clench a segment of a circular eyelet barrel, a cylindrical upsetting surface arranged to turn in and curl another segment of the barrel, a pilot portion bounded by and projecting from the inner boundaries of said upsetting surfaces, and sharp scoring edges extending along said pilot portion to the ends of said arcuate surface.

3. A tool for clenching an eyelet, the tool having an arcuate upsetting surface arranged to turn out and clench a segment of a circular eyelet barrel, a cylindrical upsetting surface arranged to turn in and curl another segment of the barrel, a tapered pilot portion bounded by and projecting from the inner boundaries of said upsetting surfaces, and divergent scoring edges extending along said pilot portion to and across the ends of said arcuate surface. v 4. A tool for clenching an eyelet, the tool having an arcuate upsetting surface arranged to turn out and clench a segment of a circular eyelet barrel, a cylindrical upsetting surface adjoining the ends of said arcuate surface, and sharp scoring edges defining the junctions of said surfaces, said cylindrical surface being arranged to turn in and curl a segment of the barrel to form a revolute lip in the mouth thereof.
